I shall leave it to others to make up some kind of silly story about where the phrase
Whole Cloth comes from. I research my etymologies very carefully. That I occasionally misplace my research and have to work from memory is a completely different matter.
The phrase
Whole Cloth is appropriate as an example. As the link provided shows, it now means "something that is wholly fabricated or a complete lie." How this meaning came from it's original reference, "to a complete piece of cloth as it is first made, as opposed to one which has been cut up to make garments," is simply another example of how a phrase can "bolt" from one meaning to another.
However, I for one cannot imagine our esteemed BK making up complete lies. He is far too honorable a man; kind, decent and generous to a fault.
I suspect that his intention was instead to use the phrase "hole cloth," which of course refers to lace. Not just any lace, no, but lace that comes from China, woven by a specialized breed of moths. These moths, relatives to the moths from which we get silk, form communities with communal minds, and work together to weave their silk into fantastical patterns. (Regular silk moths simply give us their threads, leaving the hard work of weaving the fabric to us, danged slackers that they are.) The final product is highly prized, as the fabric they produce is not only gorgeous to look at, but "breathes" and is very comfortable when worn.
It is known to unravel, however, when exposed to warm water, so I hope our esteemed BK does not cover himself with such a garment when he steps into his Jacuzzi. If he does, he will shortly find himself in an embarrassing predicament and have to dash the whole nine yards back into his comfortable abode!
